Biology
1 answer:
densk [106]3 years ago
5 0

Answer:

True

Explanation:

This is essentially natural selection. If there is a population of giraffes and half of them have long necks and the other half have short necks, the ones with long necks will be more likely to survive because they will be able to reach more leaves on tall trees. This means the ones with short necks will be less likely to survive, so when the long neck giraffes reproduce, they will pass on the gene for a long neck to their offspring. Over time, there will be more and more long neck giraffes and fewer short neck ones.

This is just a silly example but it is actually have animals have evolved over thousands of years lol

Compare asexual reproduction to sexual reproduction. In your comparison, be sure to include:
Cerrena [4.2K]

Answer:

Asexual reproduction does not involve the fusion of gametes or change in the number of chromosomes. Sexual reproduction involves combining genetic information from two individuals of different sexes. Asexual reproduction results in offspring that are genetically identical or mostly identical.

Hope this helps!

For each molecule of glucose that is processed by glycolysis and the citric acid cycle, what is the total number of nadh fadh2 m
elena-14-01-66 [18.8K]

12 is the total number of NADH FADH2 molecules that will be produced.

In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.

The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.

It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.

NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.

FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.
